Just don't say you have the stats if you don't. Don't make stuff up to make yourself look knowledgeable.
Here is a link to Al's stats. Check out his defensive rating. Starting with his second year with the Jazz his defensive rating is not bad at all. He also averages 2 blocks, nearly 2 steals, and has a very good defensive rebounding rate so obviously his defense is not horrible. All I'm asking is for you to show me the stats that proves differently. If you don't have them, shut up about it.
